Richie Wellens has denied spitting at Leon Britton during Doncaster Rovers' defeat at Swansea City on Saturday.
Swans midfielder Britton claimed Wellens spat in his face as Rovers midfielder James Coppinger received treatment on a head injury.
Wellens, who was later sent off for two bookable offences, has rejected Britton's accusations and is also unhappy that he has been branded a coward.
"I am disappointed that Leon Britton has come out in the newspapers and on the web with the accusation that I spat in his face, which he quite clearly later says was not a face to face spit," Wellens told the club's official website.
"He also called me a coward, which I found distasteful; as in 10 years and over 400 games I have never been called that.
"I did not spit in his face, but as usual I was clearing my throat and did not aim anything his way. No one, including their manager, can say they saw me spit in his face and all there had been was the usual pushing and shoving, which usually stays on the field.
"The only thing I regret was arguing with their manager Roberto Martinez as I came off when I got the red card. I should have ignored everything and walked straight off and for that I apologise."
Meanwhile, Doncaster have confirmed Coppinger is 'fine' following the incident which saw him taken to hospital after taking a blow to the back of the head.
Scans have shown up no problems for Coppinger and he travelled back to Doncaster with the rest of the squad after being released from hospital.
